Question

Why do we get isopropyl benzene on treating benzene with 1-chloropropane instead of n-propyl benzene?

Answer 1

the interaction of alkylating agent and the lewis acid leading to the formation of n propyl carbocation then n propyl carbocation being primary in nature so it undergoes 1,2 protons shift to form more stable secondary iso propyl cation...therefore isopropyl carbocation being more stable than n propyl action....so benzene later react more with isopropyl cation than n propyl cation to produce more isopropyl benzene than n propyl benzene.....hope this will help u...plzz mark as brainlist
